From renewable-powered Bitcoin mines to AI data centres: IREN’s infrastructure pivot
IREN, originally known as Iris Energy, was founded in Australia in 2018 by brothers Daniel and Will Roberts with a strategy of building data-centre infrastructure near renewable and low-cost energy.
The first major workload was Bitcoin mining, where electricity cost and data-centre efficiency directly determine economics.
IREN’s present-day business makes more sense when viewed through those early choices. The company repeatedly reused existing expertise rather than reinventing itself from nothing.
Hydropower shaped the first Canadian sites
Iris Energy developed early facilities in British Columbia using access to renewable hydroelectric power and high-voltage grid connections.
This was an important turning point because it expanded what IREN could offer or the markets it could address. The effect becomes clearer when viewed as part of the longer sequence of changes that followed.
The 2021 Nasdaq listing funded a larger data-centre footprint
Iris Energy became publicly traded on Nasdaq in November 2021 as it expanded Bitcoin mining capacity.
For IREN, access to public markets was more than a branding milestone. It increased financial transparency and created another route to fund expansion, acquisitions or long-term product development.
The IREN name reflected ambitions beyond cryptocurrency
The company rebranded from Iris Energy to IREN as it broadened its infrastructure story beyond Bitcoin mining.
This was an important turning point because it expanded what IREN could offer or the markets it could address. The effect becomes clearer when viewed as part of the longer sequence of changes that followed.
AI accelerators changed the value of powered land
As demand for GPU computing surged, IREN began deploying AI cloud infrastructure and marketing sites, power capacity and cooling capability for high-density compute.
This shift also changed how customers consumed the technology. Instead of treating software or infrastructure as a one-off purchase, the relationship became more continuous, with updates, capacity and services delivered over time.
When the scarce asset stopped being the mining machine
As of 18 September 2026, iREN now combines Bitcoin mining with AI and high-performance data-centre infrastructure built around large power portfolios.
The distance between “Hydropower shaped the first Canadian sites” and “AI accelerators changed the value of powered land” captures the larger story: IREN kept extending the value of its original expertise into new products, markets or infrastructure.
